The front post is maxed out, but it shoots a nice grouping with buis. I had a cheaper pair on it at first, and they would not line up. The magpuls ended up working. If I were going to do it over again, I would have used the stock iron sights, and left it that way. Right now, my Aimpoint is on my LR-308, so i'm using a Tru-glo red dot. Works pretty good with it, but i might put a different red dot on it.
